Introduction: The “Firewall” in Battery Manufacturing In the high-stakes world of New Energy Vehicles (NEVs), a single spark can cost billions. The manufacturing tolerance for Lithium-Ion battery modules is near zero. Traceability is mandatory—every cell, busbar, and BMS (Battery Management System) must carry a unique DataMatrix code (UDI) for lifecycle tracking. However, applying these codes presents a unique engineering challenge. You are marking energetic devices that are essentially “bombs” if mishandled. Traditional Continuous Wave (CW) or standard Q-Switched Fiber Lasers rely on thermal ablation (melting). While effective for thick steel parts, they are dangerous for: Thin-Walled Aluminum Cans:Risk of puncture or micro-deformation. Copper Busbars:High reflectivity can cause laser back-reflection or inconsistent marks. Polyimide/PET Insulation:Heat...
Introduction: The “Broken Tool” Heartbreak If you manage a mold factory or a coin mint, you know this feeling: You are 90% through machining a complex hardened steel die. The design features a microscopic serif font or a delicate hair texture on a portrait. Suddenly—snap. Your 0.2mm micro-end mill breaks. The workpiece is gouged. The tool is expensive. You have to start over. For decades, CNC Milling (Computer Numerical Control) has been the backbone of the die-making industry. It is powerful, reliable, and precise. But in the age of high-security coinage and micro-jewelry, CNC is hitting a physical wall: The Radius Problem. You cannot cut a square corner with a round tool. Enter...
